Let me tell you why I have an AR-15. From a tactical and defensive standpoint, it is highly effective for several reasons. 1) it's highly modular, 2) relatively inexpensive, 3) plethora of parts, 4) accurate and 5) it's ballistically suited for defense. Look at the pictures in Orlando, what are most of the responding officers and especially SWAT carrying? AR-15s. They are going into a close quarter area to take out a single person where there are multiple innocent people around and their choice is the AR-15. Why? Because it's efficient at carrying out this purpose. It's not a mass murdering weapon that sprays bullets everywhere. It is this same efficiency that makes the AR-15 a good defensive choice in certain situations.
Would I use an AR-15 for hunting? No. That's not what it's made for. In fact, many states do not allow you to use an AR-15 because .22 caliber is TOO SMALL for hunting. That's right, the big scary gun of mass murder uses projectiles that are too small for medium game and often over penetrate LESS than handgun rounds.
You know what would take down a lot of targets indiscriminately? A shotgun. You know the universal self-defense weapon that even Joe Biden himself recommends. A shotgun with 00 buckshot can shoot NINE little ball bearings EVERY TIME YOU PULL THE TRIGGER. So in 10 shots you can potentially hit up to 90 people. Can you do that with an AR-15?
My point is that banning a particular weapon is the wrong mindset. You take away one, people will find another avenue. There are literally hundreds of millions of AR-15s in the US and they are used in a fraction of fatalities. A call for a ban is based on emotion, knee jerk reactions, and ignorance.
I do believe we need to do a better job of keeping firearms out of the hands of felons, terrorists, etc. But that is NOT what a gun ban accomplishes.
